There is a limitation on medical negligence claims. You must, generally, bring a claim within three years of the negligence or the reasonable date of knowledge (if later). In cases involving children, it is usually three years from the age of 18. The Court has the discretion to extend this time limit but will only do so if there are exceptional circumstances, so it is important to contact us as soon as possible.. If your baby has been born with a shoulder injury, contact our medical negligence solicitors immediately to see if you have a valid compensation claim.
